Jun 23, 2015 · Image Segmentation using Otsu Method. Otsu method is a clustering based image thresholding.It works when the histogram is bimodal.The method basically tries to minimize the within class variance and at the same time it maximizes the between class variance. Total variance=Within class variance +Between Class Variance.
Image thresholding is a simple, yet effective, way of partitioning an image into a foreground and background. This image analysis technique is a type of image segmentation that isolates objects by converting grayscale images into binary images. Image thresholding is most effective in images with high levels of contrast.

Image segmentation is the process of partitioning an image into parts or regions. This division into parts is often based on the characteristics of the pixels in the image. For example, one way to find regions in an image is to look for abrupt discontinuities in pixel values, which typically indicate edges. These edges can define regions.
Mar 10, 2010 · IDX = OTSU (I,N) segments the image I into N classes by means of Otsu's N-thresholding method. OTSU returns an array IDX containing the cluster indices (from 1 to N) of each point. IDX = OTSU (I) uses two classes (N=2, default value). [IDX,sep] = OTSU (I,N) also returns the value (sep) of the separability criterion within the range [0 1].

Nov 16, 2021 · Image segmentation is the process that enables this partitioning. In this method, each pixel is assigned a label, and pixels that share some characteristics are assigned the same label number. This technique is widely used in the medical domain to locate the object of interest. It is a technique to partition a digital image into multiple segments.
